What are (5) uses for electrical stimulation? Answer - •Modulating pain
•Managing Edema
•delivering medication
•Nerve firing for muscle contraction
•Reducing spasticity
Electrical stimulation of nerve or muscles are used to evoke ___________
____________. Answer - Action Potential
(Two theories •gate theory = stimulates a nerve •Opioid theory = stimulates
release of endorphins)
What is action potential? Answer - sudden rapid alteration in the membrane
potential
What is a charge? Answer - •Depolarization and repolarization in living cells
•Can be positive or negative
What (3) things provoke action potential? Answer - •Electrical stimulation
•Nerves
•Muscles firing
,The movement of ions/electrons through a conducting medium in response to
EMF
A. Resistance
B. Current
C. Voltage
D. Ohms Answer - B (Current "A" x Resistance "Ω" = Voltage "EMF")
The rate at which electricity flows is...
A. Amperage
B. Voltage
C. Ω
D. Ohms Answer - A (Amperage)
(Amperage = current or rate of electricity flow.)
(Voltage = force that moves electricity flow)
(Ω = amount of resistance from conductor medium/electrodes, etc)
(Voltage = A x Ω)
Electrical force that moves charged particles
A. Current
B. Resistance
C. Voltage
D. Ohms Answer - C (Voltage "EMF" = current "A" x resistance "Ω")
The measure of resistance to electricity offered by conducting pathways
defined as lead wires, electrodes, and skin?
, A. Current
B. Resistance
C. Voltage
D. Ohms Answer - D (Ohms "Ω" = resistance aka impedance)
A net gain results in what kind of charge?
A. Cathode
B. Anode
C. Positive
D. Negative Answer - D (Negative charge.. Cathodes are electrodes with a
negative charge)
A net loss results in what kind of charge?
A. Cathode
B. Anode
C. Positive
D. Negative Answer - C (Positive charge... Anodes are electrodes with a positive
charge)
Which electrode has higher electron concentration?
A. Positive current
B. Negative current
C. Anode
D. Cathode Answer - D (Cathode = more attractive = negative polarity so
electrons want to neutralize it which gives a higher electron concentration than
anode)
